Interconnected stands of Aspen are actually common in areas where Aspen trees grow. Pando is just a particularly old and huge one. In the autumn, you can sometimes tell where two separate stands share a mountainside, because the clones tend to turn yellow all at once, and you can see that one side of the mountain is still somewhat green while the other has turned yellow. I lived in an Aspen forest in Park City that was like that.
